Apache httpd - a robust, open source web serverMost major Open Source software has a bewildering assortment of levels and switches when compared to commercial software - and that's because there's no restriction on development / people can make suggestions and add in facilities without the bottom line question "And what's THAT going to cost / will ...

Tuning httpd / the supermarket checkout comparisonWhy do you have multiple copies of "httpd" running on your web server, even though you have only got one process in startup? It's because httpd spawns child processes which allow it to be handling several customers at the same time rather than have them stand in line and be processed sequentially. ...

Why put Apache httpd in front of Apache TomcatDoes it seem odd to you that Apache Tomcat is a web server ... and yet the majority of sites run with another web server - Apache httpd - in front of it. Why do they do it?
There's a whole host of reasons! They including better logging, load balancing, security, speed of serving static pages such as ...

An FAQ on the Apache httpd and Apache Tomcat web servers, and on using them togetherBoth Apache httpd and Apache Tomcat are popular web servers - and most people who use Tomcat 'front' it with httpd. We run an Apache httpd course (under Linux / Unix) and also a combined httpd and Tomcat course so we're very familiar with those "Frequently Asked Questions" that everyone wants to have ...

Sticky Sessions with mod_jk (httpd to Tomcat)If you're load balancing with mod_jk, you can put a load balancer worker in your jk properties file, and then have requests forwarded to all the workers that are members of that load balancer. That's a great way to share the load.

The LAMP Cookbook - Linux, Apache, MySQL, PHP / PerlIt all started on Friday as we came back from the pub. I was describing how we've been, twice, on Neil Bauman's Geek Cruises but never been asked to talk or lecture, even in a "lightning session" on them. A little wistfully, maybe, as I'm a "wannabe" - I would love to get up and deliver a talk just ...

Keeping on an even keelSome (but not all) Open Source products have a numbering system where the second number is even for a production release and odd for a development release - so if you're looking to install one of these products on a live machine for customer use, you should make sure you stick with the even release even ...

Why run two different web serversYou wouldn't choose to use a Ford Ka as your car for that holiday of a lifetime travelling across Europe, neither would you choose a Jaguar as your idea car for the school run. Yet both of them are perfectly good models of car. Indeed as a family, you might have one of each.

Apache, Tomcat, Jakarta, httpd, web server - what are they?If someone says "Apache" to me, that's a warning - a warning to listen very carefully to what they're saying and evaluate what they mean; the term has changed - been used (and abused) over the years and it would be so easy to talk to someone, or train someone, on the wrong product.
